RIFFLE SAMPLE DIVIDER AZA0980A
The AZA0980A Riffle Sample Divider is a precision laboratory instrument designed for accurate splitting of fine and coarse aggregate samples into representative portions. Built for high-volume laboratory and field use, this heavy-duty model ensures uniform distribution, repeatable results, and zero sampling bias in construction and geotechnical testing.
This model is an enhanced version of standard riffle splitters, offering stronger construction and higher capacity collection pans, making it ideal for demanding environments.
Key Features
- Used for precise sample splitting of fine & coarse aggregates
- Uniform chute spacing for even material distribution
- Heavy-duty powder-coated steel body
- Supplied with two high-capacity collection pans
- Smooth-flow chute design to minimize material loss
- Simple, manual operation – no power required
Description
Construction & Working Principle
The AZA0980A consists of a top feed hopper and multiple precision-machined riffle chutes arranged alternately. When material is poured through the hopper, it is evenly divided through the chutes into two equal and representative samples, collected in the pans below.
This method is internationally recognized as one of the most reliable techniques for sample reduction.
Applications
-
Fine and coarse aggregate sample preparation
-
Soil mechanics and geotechnical testing
-
Cement and powder sample division
-
Mining and mineral processing labs
-
Quality control in construction projects
